Generally speaking, no, but I try to find all sorts of ways to get that information to the players during the adventure.
The intro almost always has spoilers, so I never read it to players before game. I tend to sue it to inform and supplement the Knowledge rolls and V-C's answers to questions, and I try to use it if the PCs take a prisoner. It is usually great stuff, but the trick is to find a way to bring the info ut without giving away things in advance.
